Agenda for the ninth session of the informal group working on the test procedures for the worldwide light vehicle emissions test procedure.

Paper intended to explore the inclusion of vehicle families in the WLTP GTR. In principle, global technical regulations (GTR) are restricted to technical issues such as test cycles and procedures and do not include definitions of families.

Organizational remarks and overview of the status of work of the informal subgroup working on development of the test procedures for the WLTP going into its ninth session.

Summary of the ninth meeting of the informal subgroup of WLTP working on the development of the test procedures.

Progress report of the WLTP subgroup working on lab procedures for testing of internal combustion engines.

Progress report of the WLTP subgroup working on lab procedures for testing of electric vehicles.

Progress report of the WLTP subgroup working on test procedures for particulate measurement.

Progress report of the WLTP subgroup working on the test procedures for measuring emissions of pollutants not covered by other subgroups (NO2, N2O, NH3, etc.).

Current draft annex prepared by the WLTP subgroup developing guidelines for reference fuels to be used in the light vehicle emissions test procedures.

ACEA review of issues requiring resolution pursuant to the phase 2 validation of the WLTP test procedures.

Review of the program for validation of both the new WLTP test cycle and the new WLTP test procedure towards producing a final evaluation report.

Explanation of the proposal from RDW, T&E and ICCT for an improved definition of vehicle test mass as well as the proposal from ICCT to substitute the current step-based inertia class system by a step-less approach.

Presentation on the combined approach for vehicle test weight, stepless inertia and vehicle selection developed by RDW, ICCT, and T&E.

Project schedule for the development, validation, and finalization of the global technical regulation on light vehicle emissions testing by the end of 2012.

Status of the work on drafing the global technical regulation on light vehicle emissions test procedures.
